Supergiant Star Betelgeuse

This artists impression shows the supergiant star Betelgeuse as it was revealed thanks to different state-of-the-art techniques on ESOs Very Large Telescope (VLT), which allowed two independent teams of astronomers to obtain the sharpest ever views of the supergiant star Betelgeuse. They show that the star has a vast plume of gas almost as large as our Solar System and a gigantic bubble boiling on its surface. Credit: ESO/L. Calçada
